Getting Invisalign starts with a consultation at a dentist or orthodontist who offers the treatment. From there, you’ll go through a digital scan, receive a custom treatment plan, and pick up your first set of aligners, often within a few weeks. The whole process from first appointment to final aligner typically takes 12 to 18 months, though mild cases can wrap up in as little as 6 months.
Finding the Right Provider
Both general dentists and orthodontists can be certified Invisalign providers, but there’s a meaningful difference in training. Orthodontists complete years of additional education after dental school focused specifically on tooth movement, jaw alignment, and facial structure. Many general dentists, by contrast, take a one-time training course to become certified and may only offer basic clear aligner treatment. For straightforward spacing or mild crowding, a general dentist can handle the job well. For bite corrections or more complex movement, an orthodontist is the safer choice.
Invisalign ranks its providers by volume of cases treated, with tiers like Gold, Platinum, and Diamond. A Diamond Plus provider, for instance, falls in the top 1% of all Invisalign providers in North America. Higher-tier providers have more experience adjusting treatment plans mid-course when teeth aren’t tracking as expected. You can search for providers near you on the Invisalign website and filter by experience level.
What Happens at the Consultation
Your first appointment is an evaluation to determine whether Invisalign is a good fit. The provider will examine your teeth, take X-rays, and discuss what you want to change. Invisalign works well for crowded teeth, gaps, mild to moderate overbites and crossbites, and teeth that have shifted after previous orthodontic work.
Not everyone qualifies. Severe jaw misalignment, certain complex bite problems, and significant skeletal issues typically require traditional braces or even surgery. Untreated gum disease also needs to be resolved before starting treatment, since moving teeth through unhealthy bone and tissue can cause further damage. If you can’t commit to wearing the aligners consistently, your provider may recommend a fixed option instead.
Digital Scanning and Your Treatment Plan
If you’re a candidate, the next step is a digital scan of your teeth. Most providers use an iTero scanner, which captures 6,000 images per second and builds a detailed 3D model of your mouth in just minutes. This replaces the messy putty impressions that older orthodontic methods required.
Your provider then uses that 3D model in Invisalign’s ClinCheck software to map out every stage of your treatment. The software calculates how much force each tooth needs at each step, determines the order teeth should move in, and generates a visual simulation so you can see what your smile will look like at the end. This is one of the most useful parts of the process: you’ll watch a time-lapse of your teeth shifting into position before you commit to treatment. Your provider can customize the plan, adjusting specific movements or the pace of treatment based on your goals.
Attachments and How They Work
Many Invisalign cases require small, tooth-colored bumps called attachments bonded to certain teeth. These are tiny dots of composite material, custom-shaped and positioned to give the aligners something to grip. Think of them as handles: they let the aligner apply targeted force to teeth that need rotation, extrusion, or other movements that a smooth plastic tray alone can’t achieve.
Attachments are designed to blend in with your enamel, so they’re far less noticeable than you’d expect. Not every tooth gets one. Your provider places them only where the treatment plan calls for extra force. They’re removed at the end of treatment without damaging your teeth. With attachments, experienced providers can treat most cases that would traditionally require braces.
Cost and Insurance Coverage
Invisalign pricing is generally comparable to traditional braces, though the exact cost depends on the complexity of your case and how many aligners you need. Your provider will give you a specific quote after creating your treatment plan.
If you have dental insurance with orthodontic coverage, it can offset a significant portion. Data from over 112,000 U.S. patients with dental insurance showed that coverage averaged about $1,772, with 92% qualifying for up to $3,000 in orthodontic benefits. Many providers also offer monthly payment plans, and you can use a health savings account (HSA) or flexible spending account (FSA) to pay with pre-tax dollars.
Wearing Your Aligners Daily
Once your aligners arrive, you’ll wear each set for one to two weeks before switching to the next tray in the sequence. The critical rule: keep them in for 22 hours a day. You remove them only to eat, drink anything other than water, and brush your teeth. Falling short on wear time is the most common reason treatment stalls or takes longer than planned.
Cleaning is simple but matters. Brush the aligners with a soft-bristled toothbrush using water and a small amount of liquid soap. Avoid denture cleaners and mouthwash soaks, which can damage the surface and make the plastic cloudy and more visible. Rinse thoroughly after cleaning. A weekly soak in a retainer cleaning tablet helps prevent buildup. You’ll also want to brush and floss your own teeth before putting the aligners back in, since trapping food particles against your enamel for hours is a fast track to cavities.
How Long Treatment Takes
Most people finish in 12 to 18 months. Mild cases involving minor crowding or small gaps can be done in about 6 months. More complex cases, especially those involving bite correction or significant movement across multiple teeth, can stretch past 24 months. Your ClinCheck plan will give you an estimated timeline upfront, but real-world compliance matters. Consistently wearing your aligners the full 22 hours keeps treatment on schedule; skipping hours or days adds up quickly.
You’ll visit your provider every 6 to 10 weeks for check-ins. These appointments are usually quick. Your provider verifies that teeth are tracking with the plan and hands you your next sets of aligners. If a tooth isn’t moving as expected, they may order refinement aligners, which are additional trays to fine-tune the result.
After Treatment: Retainers
Finishing your last aligner tray isn’t the end. Your teeth will naturally try to drift back toward their original positions, especially in the first year after treatment. Retainers prevent this. Most providers prescribe Vivera retainers, which are made from the same 3D scan data used for your aligners and are designed to hold your teeth in their final positions.
Retainer schedules vary by provider, but the general pattern is full-time wear initially (similar to aligners), gradually transitioning to nighttime-only wear over several months. Many orthodontists recommend wearing retainers at night indefinitely. Skipping retainers is the single biggest reason people lose the results they spent a year or more achieving.
